General Assembly of the European Geophysical Society

A space weather session was held at this year's EGS
Conference in Nice which had about 5000 attendees. The
session was organized by Mike Hapgood, Volker
Bothmer, Norma Crosby and Jan Lastovicka.
Twenty six oral and thirteen poster presentations reflect
the great resonance of the scientific community to the
space weather topic. The full day (8:30 am to 8:00 pm)
session held on Tuesday was almost continously attended
by about hundred scientists from all over the world,
mostly Europeans and Americans.
The following scientific topics were presented in the
session (not in order of priority !):
- Solar Aspects (the sun as prime source of space
weather):
P. Brekke: Space weather Effects - Towards Solar
Maximum with SOHO (solicited paper)
V. Bothmer et al.: Space weather effects of halo CMEs
S. Koutchmy et al.: Is a giant coronal cavity initiating a
CME ? (Poster)
- Radiation Hazards:
L. Dorman and L. Pustil'nik: On the probability of
catastrophic radiation hazard in space and on the Earth
from flare energetic particles

Complete author lists and abstracts are available on CD-
ROM from the EGS office.
Due to the great resonance of the authors and the high
quality standard of the contributions it has been decided
by the conveners to publish the contributions in a special
volume of "Physics and Chemistry of the Earth". Finally,
based on the success of this year's meeting, the Space
Weather Session will be continued at the next EGS
Conference in 2001, which will take place again in Nice.
Goals, amongst others, for the upcoming meeting are to
strengthen the links to the ESA space weather activities
(see http://www.estec.esa.nl/wmwww/spweather/) and the US
Space Weather Community, to enhance the number of
contributions from the fields of solar/heliospheric and
magnetospheric space plasma research and to support
ongoing and planned educational and public outreach
programmes.
